What's really missing from jQuery is animating colors. This plugin will add this feature. With this plugin, you can animate the following properties:
* color
* backgroundColor
* borderColor
* borderBottomColor
* borderLeftColor
* borderRightColor
* borderTopColor
* outlineColor
This plugin is based on Color Animations by John Resig. Unfortunately, it has a major bug which makes it unreliable. It also doesn't support the borderColor-property.
